RE: Northstar mods - Tell me what you think

My next stunt will be removing some nose weight. The CG is now located an inch or so forward of the step without fuel. I added weight slowly until I found it comfortable and reasonably stable to...

RE: Northstar mods - Tell me what you think

The takeoff run varied as I changed the tab angles. The shortest was about 200 feet in a light 2-3 knot direct crossword. I have a feeling that a different prop will improve that further. It's a...

RE: Northstar mods - Tell me what you think

Well I have an update on the 8 lb. Northstar that couldn't get off of glassy water. I went to the lake today armed with .025 aluminum, various sheet metal tools and tape. I stood around with...

RE: Northstar mods - Tell me what you think

I will try it this weekend. My plane will certainly show a difference if there is one. I already have elevons on a switch. I can turn them off and on. For some reason I never tried what you are...

Wow! That is amazing. Good luck and I look forward to hearing how it handles.

RE: Northstar mods - Tell me what you think

For those of you that might be interested in the official weight of my painted Northstar that has had trouble taking off from smooth water, I found an accurate scale to weigh it today. I haven't had...

Very nice Northstars. The pitching up is interesting. Thanks for the info. This all helps.

RE: Northstar mods - Tell me what you think

Thanks,
I'm starting to get motivated to rip the covering off my NS and get crazy with a rebuild. I have a lot of ideas now and want to try some things that will require starting over. I would...

RE: Northstar mods - Tell me what you think

I own three boats. One is a jon and two are v hull. Trust me, a flat bottom has waaaaay more drag. The only reasons boats have flat bottoms is for resting stability and clearance in extremely...

RE: Northstar mods - Tell me what you think

Oh... And how did you go about getting a 12x6 APC on there? I wish I had that option. I can only use a 10 inch prop. Don't tell my wife. Lol. I bet my .46 would turn enough RPMs in high speed...

RE: Northstar mods - Tell me what you think

I get the tail waggle with the NS too. So apparently the wing rock is not as wing loading related as I thought. Thanks.

RE: Northstar mods - Tell me what you think

What a great plane! What is your weight? That thing handles very well. I've yet to see a rotation that slow in any videos. What's your trick?

RE: Northstar mods - Tell me what you think

My thinking with the step on the tip floats is related to the manner in which a normal NS rotates in the videos I'm seeing. I'm leaning toward shaping them to a point as an alternative though. ...

RE: Northstar mods - Tell me what you think

Question...Any wing rock at half the wing loading with the Polaris? I just envision this much cleaner, slower and more friendly water handling with a moderate V on the main hull and aggressive V on...

RE: Northstar mods - Tell me what you think

That might be something to try as well. I could cut down a bigger two blade for a higher load, wider chord prop. It might give me more thrust. Only one way to find out. Thanks for the idea. ...

RE: Northstar mods - Tell me what you think

Unfortunately you will probably need to go with a four blade on a modern .60 to take advantage of the extra power. If you can find a really high pitched three blade it might work. Either way you...

RE: Northstar mods - Tell me what you think

Cougar, it accelerates well and easily planes on the main hull. As I get close to rotation speed the main hull rises and a wing will tend to drop until the tip float contacts the water again. The...

RE: Northstar mods - Tell me what you think

The builder of my NS built the horizontal stab with sticks. It is not solid, but the elevator is. I had to heat up and warp the stab back to shape as it was deformed. I'm not sure the weight...

RE: Northstar mods - Tell me what you think

Interesting thought! Although I think the high wing sweep may be the bigger culprit in this design, airflow separation due to the airfoil design itself may be something to look at. Maybe I will...

RE: Northstar mods - Tell me what you think

Thank you for your input. You bring up good points and you are being heard. I may eventually recover and lighten the NS, but not until I figure out if I can get it off the water as is. Again, I am...

RE: Northstar mods - Tell me what you think

It is not my first deltaish plane, and I am aware that the wing shape tends to have these behaviors. However I'm not convinced that they cannot be tamed. This is not really a true delta though as...
